5h On a Saturday night, Sarah Williams was walking her 9-month-old puppy around her Brooklyn neighborhood when she was approached by a man walking his dog. When the dogs became entangled and Williams attempted to extricate hers, she said the man groped her in several intimate places and pulled her toward him. She managed to wrestle herself away and “booked it” with her dog. But shortly afterward, she saw him a second time near a police station — with no police in sight. Earlier this month in Sacramento, Lauren Cooper wrapped up her noon workout and was waiting to cross the street.
